T (AZZ who/it it 77ml/ concer-71,.-

Be it known that l, GEORGE S. VARD, a citizen ol the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Cake-Machines, of which the following is a specilication, reference being had therein to l the accompanying drawing.

This invention relates to cake machines, and more particularly to a machine for depositing quantities of dough upon pans or similar receptacles.

The invention has for its object to provide a machine designed vfor depositing' predetermined quantities of dough upon pans, or a layer or quantity oi substance on the top of cakes previously formed, such as marshmellow, jelly or a like soit-substance. By the novel construction of the machine, two or more mixtures or colors oll substance can be simultaneously deposited upon cakes or two or more doughs can be deposited upon a an to form cakes.

The invention primarily aims to combine a cake vforming machine and a cake icing inachiiie, to greatly facilitate the making of cakes, cookies and the like.

To this end, the invention aims to provide a machine comprising positive and reliable means lior eil'ectiiig a perfect 'formation of a mixture upon a pan or a cake carried by a pan. .ln this connection, the invention is intended to expeditiously produce large quantities of cakes, the mechanism employed to accomplish this result being positive in its action, and free lroni danger of injury by ordinaryuse.

The machine as an entirety primarily involves in combination an endless apron mechanism having a spasmodically actuated elevating device `for raising and lowering a portion of the apron, and a ratchet device for intermittently moving said apron, a dough or mixture hopper having an intermittently i mixture-'feeding mechanism, and an interchangeable die-plate having means for posi- 'j tioning, temporarily holding, releasing and delivering a quantity of dough or mixture i, to receptacles carried by the interminable l apron. l j The above elements, together with their j respective mechanisms will be hereinafter described in detail, and specially pointed out in the claims.

ln describing the invention in detail, reference will be had to the accompanying drawings, vforming part of this specification, and wherein like numerals ol reference will be employed to designate corresponding parts throughout thc dill'erent views, in which Figure l is a side elevation of my improved machine, Fig. 2 is a front elevation of arocker-arm constituting a part of the apronactuating mechanism, Fig. 2 is a detail View of disk used with the machine. Fig. 3 is an elevation oi" the interior mechanism of a ratchet employed in connection with the mixture ieeding mechanism, Fig. t is a vertical sectional viewoi the same taken on the line of Fig. 3, Fig. 5 is a longitudinal sectional view of the machine, Fig. 6 is a plan of the same, Fig. 7 is an enlarged fragmentary plan of the dough or mixture hopper, the inner driven rolls thereof being removed Fig. 8 is a plan of the inner driven roll of the hopper, Fig. El is a transverse vertical sectional view of the same taken on the line fy-'y of Fig. 8, Fig. l0 is a plan of a detachable die-plate adapted to be supported `from the hopper of' the machine, Fig. 11 is an end view olE said plate, Fig. l2 is an enlarged vertical sectional view of one of the dies of said plate, Fig. 13 is plan of a die holding ring, Eig. la is a longitudinal sectional view, partly in elevation, of a pitman-rod stroke adjuster, Fig. 15 is a similar view ol a portion of' the same, Fig. 16 is a vertical sectional view ol' the hopper of the machine, the 4inner driven rolls thereof being removed, Fig. 17 is a perspective view of a vertically reciprocating i'rame, constituting a portion of the apron elevating device, Eig. 1S is a similar view of one of the detachable bottom plates of the hopper,

To put my invention into practice, l. provide a suitable support for the mechanism, a convenient form being shown in the'accompanying illustration, and embodies two metallic side frames l and 2, secured together by tie-rods or stays 3, located at suitable places to give the desired rigidity to the frame support. Each side frame comprises top rails 4, bottom rails 5, vertical end standards 6 and intermediate standards 7.

Supported on the top rails 4 centrally of the machine by brackets or Vl'eet 8, is a dough or mixture hopper 9. As it is :frequently desirable to place two difierent colored substances or two difl'ei'ent mixtures in the hopper, it is preferable that this hopper be separated into two compartments, and when this is donc, it is preferable that the dividing par- IOO tition be made removable, also the sides 11 and the bottom plates 12, this construction permitting of the hopper being easily cleaned. In carrying out this arrangement of parts, the end walls 14 are provided with inclined grooves 15 to receive the sides l1, l and with horizontal grooves 16 to receive the l bottom plates 1.2, said plates being grooved, as

at 1.7, to receive the bottom edges of the sides 11. The end walls 14 are cut away to form guideways 18 to accommodate a roll housing 19, the end plates 20 of which are flanged, as

at 21, and carry the partition 10. To brace the end walls 14, the tie-rods 22 are employed, and in connection with a feed plate 23, form a rigid structure upon the side frames l and 2. The feed plate 23 is formed with converging curved slots 24 longitudinally of said plate, and between the slots is a central transverse grooved support 25 for the partition 10. The sides of said support are curved, as at 26 to receive the inside pair of feed rolls to be hereinafter described. This feed plate acts as a scraper to remove the dough from the rollshrom the slots 24, the contents of the hopper pass through a die-plate 27 and spring dies 28. The feed plate 23 at its transverse edges is provided with a guide-way or cleat 29 and depending bolts 30, the edge 31 of the die plate fitting in the guide-way 29, while the bolts 30 engage in slots 32, formed in the opposite edge of the die plate. By this construction, the die plate 27 can be readily removed to permit of various other die plates being used, where cakes of various sizes and congurations are to be made. ln thedieplate is formed a plurality of openings 33,

said openings being arranged in two rows to aline with the slots 24 of the feed plate 23.

Suspended from the plate 27 by holding rings 34 are sleeves 35, these sleeves together with sleeves 36 constituting the dies 28. The sleeves 36 telescope the sleeves 35 and are supported upon a plate 37 loosely suspended by bolts 38 from the die plate 27. Surroundlng said sleeves are coiled springs 39, said springs normally holding the plate 37 at the lower ends of the bolts 38. Secured to the transverse edges of the plate 37 are depending bars 40, the object of which will be presently described.

To temporarily retain the contents of the hopper 9 within the dies 28, the lower ends of the sleeves 36 are contracted, as at 4l, the contents being partially ejected when the plate 37 is elevated. To facilitate the pas- I sage of dough or a mixture in the slots 24, l journal corrugated rolls 42 in the end walls l 14 of the hopper, and similar rolls 43 in the end plates 2O of the roll housing 19, the confronting rolls being revolved toward one another and toward the slots 24 of the hopper. The one end of each roll is provided with a gear wheel, the gear wheels 44 of the rolls l 42 meshing with the gear wheels 45 of the rolls 43.

Upon the ends of the rolls 42 contiguous to the gear wheels 44 are mounted box ratchets 46 (see Figs. 3 and 4l these ratchets being operated by connecting-bars 47 eccentrically and adjustably connected to the outer sides of the casings 48 of said ratchets. The ratchets are of a conventional form consisting of a ratchet-wheel 49, a spring-held pawl 50 and a spring pressed. locking stirrup 51, these parts being assembled to impart an intermittent movement to the rolls 42 and 43.

The construction ofthe hopper as above described., permits of one compartment of the hopper being used independent of its associate compartment, and allows the die plate 27 to be replaced by a plate containing dies that can be fed from both of the slots 24. lt is, therefore, apparent that cakes can be produced composed of two kinds of dough of' mixtures, each of which is separate until fed into the dies of the die-plate.

Reference will now be had to an endless apron 52, employed for carrying pans or trays upon which the dough or cake mixture is deposited, these pans being conveyed from the front end of the machine, to the rear end thereof, and temporarily held and elevated beneath the hopper of the machine. The endless apron or belt 52 is fricticnally mounted upon rollers 53, 54 and 55 ournaled in the side frames l and 2 of the machine. The roller 54 is journaled in bearing blocks 56 adjustably mounted by hand-screws 57. The one end of the roller is provided with a handwheel 58, whereby the apron can be manually moved at any time. The rollers 55 simply serve as guide-rollers, while the roller 53 acts as a drive roller for the apron. The end of this roller is provided with a simple box ratchet 59, which is oscillated by a pitmanrod 60, to move the apron 52.

The device employed for raising and lowering that portion of the apron beneath the hopper 9 comprises a vertically reciprocating table 61, said table being approximately the same length as the machine and supported in a horizontal plane beneath the apron 52. The table is supported and guided in its movement by T-shaped legs 62, the lower ends of said legs being slidably mounted upon the inner sides of the frames 1 and 2 between guides 63 carried thereby. Extending through the legs 62 near the table top is a shaft 64, the ends 65 protruding through the slots 66 formed in the upper ends of the intermediate standards 7 of the frames 1 and 2. The ends of the shaft 64 are provided with guide blocks 67, which slide in the slot 66, and the extreme ends of the shaft serve functionally as trunnions to which are connected adjustable pitman-rods 68.

To maintain a frictional engagement between rollers 53, 54, 55 and apron 52, and at IOO ening' roller is lowered.

thesame time allow the apron to be raised by the table 61, l employ a compensating device embodying` an adjustable tig-.itening roller 69, said roller being journaled between arms carried adjacent to the ends ot a shaft 7 l, revolubly mounted above the apron 52, between the 'frames 1 and 2. 'lhe shalt 71 is provided with a central rearwardly extending arm 72 adapted to engage the transverse sha'lt 64 carried by the legs 62 ol" the table 61. lVhen the table is raised, that portion ot the apron resting upon the tight- Now, to operate the pitman-rods 60, 68 and connecting bars 47, .l employ a mechanism which is driven Yl'roin a shat't 7st. The one end ot' the shat't 74 carries a crank arm 75, which is connected by a rod 56 to a rock arm 77 pivotally mounted upon the 'frame 1. The rock arm 77 is provided with adjustable blocks 7S to which the pitman-rod 60 and rod. 7 6 are pivotally connected. The blocks 7S are adjusted by screws 79.

The shal't 74 adjacent to crank arm 75 is provided with an eccentric 80, saideccentric connecting by a rod S1 with a crank arm S2, carried by a shalt 823 journaled in the rails 5 ol" the trames l and 2. The shaft S3 has its ends provided with crank arms 84, to which the pitman-rods 68 are adjustably connected. '.he rod S1 is provided wit-h a stroke adjuster S5 (see Figs. lll and 15) consisting ol: a cylindrical casing 86, housing' a barrel S7. Surrounding the barrel S7 is a spiral spring S8, which cushions the forward stroke of the rod S1. The end ot' the rod is adjustably mounted in the barrel and retained therein by lock nuts SS).

rlo operate the connecting bars 47, the sha'tt 74 is provided with a central sprocket wheel and passino' over said wheel is an endless chain lll, which also embraces a sprocket wheel Q2 mounted upon a shalt 93, journaled in the rails 5 ol the 'trames l and 2, adjacent to the intermediate standard 7. Mounted upon the ends of the shalt 93 are disks 94 to which the ends ol the bars 47 are eecentrically and adjustably connected.

The end of the shaft 741 protruding from the side frame 2 is provided with belt pulleys 95 by whicl'i` the shaft 74 is driven. ln order that the machine, when in operation may be easily and quickly stopped by an operator at the 'forward end o'l.: the machine, lV mount a conventional 'Form ot' belt shifter 96 between the `trames 1 and 2, said shilter having an arm Q7 by which it can be actuated by the limb ot the operator.

lVhen the machine is in operation, the operator stands at the 'forward end ot the ma chine and places the pans or trays upon the apron 52. As the apron is intermittently moved, the pans will be temporarily held stationary a number otl times beneath the hopper 9. it is during this interval that the apron is elevated through the medium of the verticallyreciprocating table 61, to allow a pan to receive a deposit ol dough from the hopper 9. When the apron and table are elevated, the pan carried by the apron strikes the bars -lO of thedies 2S and elevates the sleeves 36 ol" said dies, causing a quantity el' dough to be precipitated upon the pan. rlhe rolls 42 and 43 are adjusted to operate in unison with the elevating ol' the apron 52, whereby a quantity olf dough will be moved into the slots 2e. "his is accomplishedv through the medium olt the disks lll, (see Figs. 1 and Il) which are adjusted by the bolts S141 'of said disk. Vlmmediately upon the table, apron and pan receding, the sleeve 236 and bars et() assume their normal position, con'lining the plastic dough until the table Gl is again actu-l ated through the medium ol the pitman-rods (3S, crank shalt S3 and eccentrics S0. To liacilitate a rapid withdrawal ot the pans trom the bars Li0 and thus sever the dough, l'. provide the crank shafts 83 with a lever 9S carrying an adjustable vweight 9S). Alter the table 61 has receded, the apron 52 upon the table is moved a prescribed. distance and again elevated to allow another row of' deposits to be made upon a pan. W'hen the pan has been lilled, it is conveyed to an oven (not shown) located in close j )roximity to the machine. vDuring the above operation, the dough or mixture contained 'within the hopper is automatically l'ed to the spring dies 2S ol" said hopper.

The machine thus lar has been described as a cake-making machine, but it is obvious that by certain adjustments, the machine can be readily used as an icing machine. 'lo this end, the pitmanrods (5S are regulated to raise the cakes placed in a pan or upon the apron, a prescribed distance .in order that a proper coating may be placed upon the cakes. The connecting bars -l7 are also adjusted at the disks 94, to properly Aleed the icing or coating to the dies 28.

1t will be apparent 'lrom the l'oregoing description that l have devised a novel cake machine for expeditiously lorming cakes, and l4 desire it to be understood that such changes in the arrangement of operating' mechanism as are permissible by Ithe appended claims, may be resorted to without departing l'rom the spirit and scope of the invention.
